#989 feat(blog): show writer reviewer editor on human articles

Summary

Human-written blog articles now show a three-person editorial credits block (writer, reviewer, editor) instead of a single author line. AI articles keep the existing single-author byline when frontmatter sets origin: ai.

Changes

• Add shared HUMAN_EDITORIAL_TEAM constant with Martin (writer), Valeria (reviewer), and Jordan (editor)
• Add BlogEditorialByline and BlogAuthorByline components
• Gate display with optional origin frontmatter (human default; ai keeps legacy author UI)
• Add i18n keys: article_credits, blog_role_writer, blog_role_reviewer, blog_role_editor

Coordination with human/AI listing PR

This PR only handles the byline UI. A separate PR can tag posts with origin: human | ai. Until then, posts without origin are treated as human and show the editorial team.

Test plan

• bun run build in apps/web
• Verified /blog/capacitor-comprehensive-guide/ shows three-person credits
• Posts with origin: ai should keep single-author byline (once tagged in the listing PR)
